Three class groups, Vaccinio-Piceetea, Acero-Fagetea, and Lauraceo-Fagaceetea sempervirens are the major zonal forest communities of Japan. Moreover one must add two outsider orders, Tsugetalia sieboldii and Pinetalia densiflorae. Orders are suitable elements for mapping in a smaller scale. The alpine pine scrub, Vaccinio-Pinetalia is shown in pale rhodonite pink and the subalpine coniferous forest, Betuletalia ermani in lavender violet. The montane beech forest, Saso-Fagetalia is coloured in vandyke brown, while the edaphic community, Fraxino-Ulmetalia in light rosolane purple. But when one goes gradually southward, or descends downward, reconstruction becomes more and more difficult and the result proves to be artificial, so that the occurrences of the natural forest of the Shiion sieboldi and the suballiance of Quercion phillyraeoidetis, should be marked motmot green and snuff brown dots, and the areas of the Oryzetea sativae are drawn in Mathew's blue, and those covered by the Miscanthetea sinensis in dull green yellow. The submontane forest of Tsugetalia sieboldii in Persian blue and the lowland and coline coniferous forest of the Pinetalia densiflorae in pinard yellow. On the summits of mountains in Kyusyu and Sikoku, grassland with dwarf shrub growth, Rhododendron kiusiani are represented in small Tyrian rose dots. Besides the secondary forests of deciduous oak and chestnut develop in very wide range and the areas are coloured in ochraceous buff.

On core samples taken from 907 meter boring penetrating the Quaternary-the middle Tertiary sediments at Tanakamoto-machi, Minato-ku, Osaka, total organic carbon, alkaline soluble organic carbon, humic acid, and fluvic acid have been analysed. The absorption spectra of humic acids extracted from those samples have been examined. The results obtained are as follows: 1) Except for samples containing substantial amount of plant residues, total organic carbon contents of core samples ranged from 0.1 per cent to 1.5 per cent, of which values had little difference compared with those of recent sediments in Osaka Bay. These results were not closely related to the increasing depth or facies of sediments. Accordingly it could be concluded that total organic carbon content in sediments might strongly reflect autochthonous organic matter content supplied into the sediments. 2) Alkaline soluble organic carbon contents, with a mean of 0.26 per cent, did not vary with an increase in depth. 3) There was a slight decrease in amounts of humic acid but not in amounts of fluvic acid with depth. 4) Sediments contained more fluvic acids than humic acids in quantity. 5) The patterns of absorption curve of the humic acids extracted from these sediments were roughly similar to those from soils. 6) Values of RF of humic acids varied from 49 to 145. Values of Δlog K of humic acids (log K_<400>-log K_<600>) ranged from 0.5 to 0.9 with a mean of 0.7. Supposing the degree of humification of humic acid indicated by these values, humic acids extracted from core samples are considered to have been moderately humified.
